Flexible even at temperatures as low as -80° F, these fluorosilicone O-rings will keep your fittings free from leaks. They’re often used on fuel and coolant hose because fluorosilicone resists many chemicals, including ethanol and ethylene glycol.

These U-cup seals create less friction than O-ring-loaded U-cups, so they wear more slowly. Also known as lip seals, U-cups have a sealing lip on both the inside and outside edges, so they can be used for rod and piston sealing.

A square O-ring prevents these piston seals from rocking in the groove.

Rated for pressure up to 10,000 psi, these seals withstand the highest pressure of our piston seals.

Avoid common O-ring failure in dynamic applications—the square base of these seals prevents twisting, while backup rings protect against extrusion.

For use in air-powered cylinders, these seals prevent the piston from slamming against the cylinder body to minimize wear and noise.

A two-lip design means that these wipers also function as a rod seal.

Made from MDS-filled PTFE for a slippery surface, these wipers allow rods to move three times faster than other rod wipers.

Made from glass-filled nylon for excellent wear resistance and strength.

Designed with an extended lip, these seals have the flexibility to accommodate shaft misalignment up to 0.125". They're also known as clipper seals.

An extended spring on these seals accommodates variations in seal cavity length and pump misalignment.

Multiple internal springs ensure these seals keep the sealing surfaces in contact in demanding applications, such as agricultural, chemical, and mining pumps.
